Spanking

When the DohlmanElaan warned CaptainJames T. Kirk never to touch her again, Kirk responded with a warning of his own, with regards to her tantrum like behavior, remarking that "if I touch you again, Your Glory, it'll be to administer an ancient Earth custom called a "spanking," a form of punishment administered to spoiled brats." (TOS: "Elaan of Troyius")

When Spock established that V'ger was merely a child, and as such, should be treated as a child, Leonard McCoy reacted to Spock's understatement, exclaiming, "that thing is about to wipe out every living thing on Earth, now what do you suggest we do? Spank it?" (Star Trek: The Motion Picture)
